WILLIAM WHEELER, OF CONCORD, MASSACHUSETTS.

REFLECTOR FOR STREET LAMPS OR LANTERNS, 840.

SPECIFICATION forming part of Letters Patent N 0. 268,063, datedNovember 28, 1882.

Application filed June 6, 1882. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM WHEELER, of Concord, in the county ofMiddlesex and State 'of Massachusetts, have invented a new and versesection, on an enlarged scale, of one of the metallic fillets or beadedbands used for holding in place the series of glass reflectingplatesapplied to the inner surface of the shell of the reflector. Fig, 7 is atransverse section, on an enlarged scale, showing the arrangement ofsuch fillet, with the shell, its flange, and a glass reflecting-plate.Fig. Sis an under side view of a portion of such fillet. Fig. 9 is avertical and longitudinal section of the reflector.

The nature of my invention is defined in the claims hereinafterpresented.

In the drawings the reflector is exhibited as having four conical orapproximately conical reflecting-surfaces,arranged as shown, two ofthem-via, the upper and lower ones, a and b.being convex semi-frustums,while the others or intermediate ones, a and d, are concavesemi-frustums. YVithin the reflector, and concentric with its lowerreflecting portion, a, is an open chamber or socket, A, for holding anoil or kerosene lamp, B, in its proper position relative to the saidreflecting-surfaces. Over such chamber or socket, and in the upperportion of the reflector, is an opening, 0, for the glass chimney I) ofthe lamp to extend through, allbeingsubstantially as represented. At thelower part of said opening there projects from the reflector a hook orstud, e, which, with the front part of the opening, serves to supportthe chimney on its being raised into the positionshown in Fig. 5 toadmit of the lamp being removed from the reflector and trimmed withoutthe necessity at the same time of removing the chimney therefrom. Toprevent accidental breakage or injury to the lamp-chimneys, they arefrequently left in the street-lanterns while the lamps are taken or areaway therefrom for being trimmed or supplied with oil. The object of thehook or stud, arranged as described, will thus be apparent.

The shell E of the reflector has narrow flanges h h, extending from itat its inner and outer edges, bounding the series of reflecting glassplates In. There is arranged within and against each of the said flangesa flexile metallic fillet, I, having on' its inner surface, andlengthwise thereof, a bead, m, such beaded fillet being represented intransverse section in Fig. 6. These fillets I usually make of lead.After having been soldered at one edge ofeach to its supporting-flangeh, the fillets are to be bent down upon andover the glassreflectingplates at their ends, which are to abut against the beads,each head serving to prevent its.

fillet, when bent down, from having or presenting a corrugated orangular outline on its outer surface, as it would be liable generally tohave Without such bead.

Instead of having the head in one piece with the rest of the fillet, Isometimes make it in a separate piece.

With a reflector made as described rays of light from the flame of thelamp will be refiected laterally in opposite directions from the partsor reflecting-plates in rear of the lamp, while from those iii-front ofand above the lamp the rays will be thrown or reflected in divergentlines.

. My present invention has special reference to reflectors for use withcommon lamps for tric lights or carbon pencils therefor.

What I claim as myinvention is as follows, viz

1. The reflector as constructed with the two convex conicreflecting-surfaces a b, the two concave conic interveningreflecting-surfaces c d, the chimney-opening O, and the lampoilreservoir-receivin g socket A, arranged substantially as set forth.

2. The reflector as constructed with the two convex conicreflecting-surfaces a b, the two intervening concave conicreflecting-surfaces c d, the chimney-opening G, the chimney-supportinghook or stud e, and the lamp-reservoirreceiving socket A, as andarranged substantially as set forth.

3. The reflector-shell provided with flanges and reflecting-platesarranged between them,

and with metallic fillets and beads or metallic beaded fillets,essentially and arranged with :0 the said flanges and reflecting-platesas set forth.
